英文AIDS关于艾滋病.ppt

Genetic research indicates that HIV originated in west-central Africa during the late nineteenth or early twentieth century. AIDS was first recognized by the U.S. Centers for Disease Control and Prevention in 1981 and its cause, HIV, identified in the early 1980s. AIDS is now a pandemic. AIDSHIV＆Acquired Immune Deficiency Syndrome.What is AIDS?AIDS is a medical condition. A person is diagnosed with AIDS when their immune system is too weak to fight off infections.AIDS stands for:AIDS is a retrovirus infection caused by the body's immune defense system diseases. In a normal human body, the immune system plays a good body of the “defensive“, various pathogens to resist the attack.But one HIV-infected, a good body defense system will be destroyed, defense dysfunction. Then microbial pathogens and thus able to drive straight into the opportunity Hematogenous wounds and broken.艾滋病毒(人类免疫缺乏病毒) Incubation period of AIDS symptoms proportion(艾滋病潜伏期症状比例)80% 80% Fever(发热) 70% 70% Lethargy and general discomfort (嗜睡和全身不适 ) 50 - 70 % 50 - 70 % Muscle pain and joint pain(肌肉痛和关节痛) 40 - 70 % 40 - 70 % Enlargement of lymph nodes(淋巴结肿大) 50% 50% Night sweat(盗汗) 50 - 70 % 50 - 70 % Gastroenteritis(胃肠炎 ) Diarrhea(腹泻) 30% 10 - 30 % Dental ulcer(口腔溃疡) 40 - 70 % 40 - 70 % Nerve headache(神经性头痛) 40 - 80 % 40 - 80 % Rash(皮疹) 5 - 15 % Genital ulcer(生殖器溃疡 ) 45% Thrombocytopenia(血小板减少) 40% Leukopenia(白细胞减少) 20% Transaminase rise(转氨酶上升)WHO reported that in 2010, survival with HIV and AIDS worldwide is totally accounted of 34 million patients, 2.7 million new infections, 1.8 million annual deaths. Every day there are more than 7,000 new infections.In 1995, Chinese-American scientist David Ho proposed the “highly active antiretroviral therapy.”（高效抗逆转录病毒 治疗方法） It is like a cocktail configuration process, so called “cocktail therapy.” （鸡 尾酒疗法）Although it cannot help to completely cure, but to reduce mortality successfully and significantly; morbidity time will be postponed indefinitely, and the number of viruses that infected individuals can be reduced to the status which can not be tested, thereby improving the health of carriers significantly.November 2005, according to the BBC and some newspapers, said: a 25-year-old male inhabitants of London, Andrew Simpson, who in May 2002 confirmed infected with the AIDS virus, but did not carry out any medication was found that the virus has disappeared in an inspection in October 2003 . He may be the first one heal on their own HIV-infected persons. Recovery case IAccording to U.S. media November 12, 2008, reported that after a patient suffering from leukemia and AIDS receiving stem cell bone marrow transplant, the HIV virus in the body should have all disappeared.Recovery case II1、Daily contact, like shake hands or share one tool will be infected with AIDS.3、AIDS/HIV is an excuse to genocide.2、 Insects bites will cause HIV/AIDS1. Mother-to-child transmission 2. Sexually transmitted 3. Transmitted through bloodMother-to-child transmissionThe transmission of the virus from the mother to the child can occur in utero （子宫）.Sexually transmittedThe majority of HIV infections are acquired through unprotected sexual relations between partners, one of whom has HIV.Transmitted through blood.the same syringe drugs, input containing the AIDS virus blood and products, etcThe difficulties of making AIDS/HIV vaccine?1、There’s no animals models suitable for initial test.2、It’s danger to use live-virus vaccine, it may cause more infection.3、There’s still no complete genetic system to against the virus.4、Humans’ immune system couldn’t clean out all the virus. 5、HIV’s variation ability is hyperactive. It will cause many unpredictable disease.6、Irrational fear and hostility directed at a minority 1、There’s no animals models suitable for initial test.2、It’s danger to use live-virus vaccine, it may cause more infection.3、There’s still no complete genetic system to against the virus.4、Humans’ immune system is not strong enough to clean out all the HIV virus. 5、HIV’s variation ability is hyperactive. It will cause many unpredictable disease.6、Irrational fear and hostility directed at a minorityDec. 1stOrigin: The first AIDS patient was found on Dec.1st, 1981 1988 World Summit of Ministers of Health on Programmes for AIDS Prevention(全球卫生部 大臣关于艾滋病预防计划的高峰会议)Aim: 1.Control & prevention 2. resbonsibility 3.sympathy and understanding 4. Join the Worldwide EffortIn 1985, the first AIDS patient was found in China.In 1989, it was first reported in Yunnan that drug addicts were infected with AIDS.In 1995, those who sold their blood in Henan were infected with AIDS.In 2006, China began to put the Prevention and Treatment of HIV/AIDS(艾滋病防治条 例)into practice .L'Oreal organized the activity named “we are the same” .RED, a non-government institutionThe chari。
